【摘要】：对于电光源来说,“绿色照明”已经是照明行业的一个新的标志。无极灯是近年发展起来的新型光源,它是基于电磁感应的原理,没有灯丝,没有电极,具有长寿命、光效高、显色性高等优点,广泛应用于道路、隧道、桥梁、体育场、展览场馆等。光效的提高不仅仅意味着更加节能,也意味着无极灯工作稳定性大大改善。本课题在此背景下展开无极灯光效影响因素分析研究,试图通过研究泡体温度,寻找提高无极灯光效的方法。 无极灯是利用耦合器将高频发生器的电磁场以感应的方式耦合进泡体内部,使泡体内的气体雪崩电离,产生等离子体激发荧光粉而发光,等离子体的分布状态直接影响光效的高低。本文主要做了如下工作：1)通过分析温度对磁耦合器稳定性的影响确定出在10。C到125。C范围内,耦合器的性能相对平衡,并且为了深入研究本文利用MATLAB对耦合器电磁场进行建模与仿真,省去了因各个参数不同带来的大量正交实验。2)光效测量装置的搭建,通过实验确定出最佳探测距离以及最佳探测口径的大小,根据测量的要求,实现对泡体不同位置光效值的采集,设计出便于携带,测量精度高的光效测量装置,并对本装置进行标定。完成对温度测量系统的确定,采集无极灯泡体不同位置的温度值。3)通过实验设计,确定出探测温度以及光效的最佳测量方案。 最后通过实验数据分析比对确定出温度如何影响光效,并结合之前对磁耦合器分析的实验所得出的温度范围,确定出光效最高时的温度范围为100℃到125℃。
[Abstract]:For electric light source, "green lighting" has been a new symbol of lighting industry. Pole-less lamp is a new light source developed in recent years. It is based on the principle of electromagnetic induction, no filament, no electrode, long life, high light efficiency. The advantages of high color rendering are widely used in roads, tunnels, bridges, stadiums, exhibition venues, etc. It also means that the working stability of the electrodeless lamp is greatly improved. Under this background, the paper analyzes and studies the influencing factors of the light efficiency of the electrode free lamp, and tries to find a way to improve the light efficiency of the lamp by studying the temperature of the bubble. The electrodeless lamp uses the coupler to couple the electromagnetic field of the high frequency generator into the bubble body in an inductive way, so that the gas avalanche in the bubble is ionized, and the plasma excites the phosphor to emit light. The distribution state of plasma directly affects the light efficiency. The main work in this paper is as follows: 1) by analyzing the influence of temperature on the stability of the magnetic coupler, it is found that the performance of the coupler is relatively balanced in the range of 10.C to 125.C. And in order to deeply study the modeling and simulation of coupler electromagnetic field by using MATLAB in this paper, a large number of orthogonal experiments. 2) the light efficiency measuring device, which is brought by different parameters, is eliminated. According to the requirements of the measurement, the collection of light efficiency values at different positions of the bubble body is realized, and a light efficiency measuring device is designed, which is easy to carry and has high measurement accuracy. The device is calibrated. The determination of the temperature measurement system is completed, and the temperature values of different positions of the polar light bulb are collected. Through the experimental design, the best measuring scheme of the detection temperature and the light efficiency is determined. Finally, by analyzing and comparing the experimental data to determine how the temperature affects the light efficiency, and combining the temperature range obtained from the previous analysis of the magnetic coupler, it is determined that the temperature range of the highest light efficiency is 100 鈩，
